Swaged Jacketed Piping

In swaged jacketed piping, the jacket is terminated prior to the flange. This is accomplished via a jacket-sized pipe cap which is welded to the core pipe a short distance from the back of the flange.

The principal benefit of this construction is the ability to use core-size flanges on both piping and mating equipment. Using equipment with standard, core-size flanges favorably impacts the cost of a piping system. Another benefit is the ability to significantly limit the potential for cross contamination by avoiding concealed welds. Because swaged jacketed piping does not directly provide heat to the back of the flange, its usage is limited to processes which can accommodate a broader temperature range and colder flanges. If swaged construction is chosen but additional heat is required at the flanges and/or fittings, ControHeat® bolt-on jackets can be used in these locations to prevent cold spots.
